摘要: To provide a highly functional yet very compact retractable reel assembly for telephone extension cord, housing is provided which adapted to be mounted on wall in proximity or jack utilization with either table telephones, respectively. The includes biased rotation one direction, ratchet selectively restraining of the and an expansion chamber length cord within housing, whereby portion leading can normally wound radially axially confined planar helical array. With this arrangement, allow repositioned expanded array during withdrawal remainder from returned retraction into housing.
